Summary: This study explores the impact of dam re-operation strategies on reducing hydrological alterations in the Lower Mekong and highlights the corresponding opportunities and limitations. The findings suggest that focusing re-operation efforts on the lower Mekong can partially restore key elements of hydrological variability without hindering hydropower production, and bring economic benefits.

Summary: The study highlights the importance of linking biogeochemical processes to water flow paths and solute travel times for understanding internal catchment functioning and water quality control. By modeling base cation export using a fully calibrated 3D hydrological model and water chemistry data, the results show that catchment hydrology and landscape properties primarily control weathering rates and stream dynamics.

Summary: This study adopts a novel approach to refine and map the sediment source zones within the Bowen catchment by integrating three independently derived sediment budgets, targeted tributary water quality monitoring, and geochemical sediment source tracing. The field data and finer resolution predictions have identified the Little Bowen River and Rosella Creek as the largest sediment sources in the Bowen River catchment. The use of integrated datasets provides a higher level of certainty in predicting fine sediment sources and can inform catchment management prioritization.

Summary: Desert riparian vegetation plays an important role in ecological water conveyance and biodiversity conservation. This study analyzed the ecological restoration status of the Tarim River from 2015 to 2021 and found that ecological water conveyance has contributed to groundwater recharge and restored desert forest ecosystems. The overall habitat status and ecological environment quality have improved significantly.

Summary: Impacts of climate-related water stress and temperature changes can have cascading effects on energy systems. However, current models have not fully captured the compounding of these effects. In this study, a coupled water-power-economy model was used to examine the exceedance of water temperature thresholds for power generation in the western United States. The results showed that not all reductions in reserve electricity-generation capacity lead to impacts, and intermittent interruptions in electricity supply at critical times played a significant role in economic impacts. Additionally, the impacts may occur in different locations from the original water stress. It was estimated that the consumption loss could be up to 0.3% annually, and the identified drivers in the coupled modeling could increase the average cost of electricity by up to 3%. Integrated models are necessary to capture the cascading effects of climate change on climatic, water, energy, and economic systems.

Summary: This study investigated the relationship between meteorological drought and e-flow releases in eight catchments of southern Poland. The results showed a significant decreasing trend in streamflow rate in the Skawa sub-basin, while an increasing trend was observed in the Biala and Sekowka catchments of the Dunajec sub-basin. The study demonstrated the potential of SPI and PNI indices as helpful tools in water resources management and planning, particularly in predicting the impact of droughts on e-flows deficit.

Summary: This paper presents an analysis of the problems associated with calculating environmental flows (EFs) using different hydrological methods. The analysis was conducted in 14 catchments located in the Vistula and Oder River basins in Poland. The results showed that the different methods used were sensitive to the length of the hydrological time series, and there were significant differences in the EF values calculated for different periods. The study also observed the impact of hydrological drought on EFs, as well as the variations in water deficit characteristics depending on the method used for EF calculation.

Summary: This study compares the simulated streamflow composition of three well-known rainfall-runoff models (ECOMAG, HBV, SWAT) with the hydrograph decomposition evaluated using End-Member Mixing Analysis (EMMA). The study finds significant differences in the runoff sources dynamics between two neighboring catchments. ECOMAG is the most conformable to the EMMA outcome, HBV reflects flood events well, and SWAT exhibits distinctive behavior compared to other models. The results show that, in addition to the standard efficiency criteria of simulated and observed runoff proximity, EMMA analysis can provide useful auxiliary information for the validation of modeling results.

Summary: The study examines the impact of transport infrastructure investment on environmental degradation in selected Asian countries. GDP positively affects environmental degradation, while GDP(2) and GDP(3) have negative effects. Road infrastructure investment has a positive effect, while railway infrastructure investment has a negative effect on environmental degradation. Air infrastructure investment and trade opening have a gradually increasing impact on environmental pollution.

Summary: This paper proposes a systems-thinking framework for evaluating investment impacts in potable water infrastructure (PWI) using a more systematic and comprehensive approach. The framework can be applied to any PWI investment question, providing analysts with a broader understanding of the impacts. The study validates the method and introduces a new rating called flow betweenness to evaluate the prominence of each impact within the PWI socio-economic system.

Summary: This study improves the methods of predicting the streamflow impacts of alien tree clearing and explores the variability in catchment responses at a fine-scale. The findings show that clearing mature infestations of alien trees can increase surface water resources, and clearing riparian invasions has a greater impact compared to terrestrial invasions. The study also highlights the largest impact of restoration on mid to low flows and a greater impact in dry years.

Summary: Established in 1935, the Jonkershoek Forestry Research Station in South Africa's Mediterranean climate region conducted experiments on afforestation's effects on water yield. Demonstrating significant impacts on streamflow, the research has influenced environmental policies and practices in South Africa and beyond. The experiment continues to be maintained by the South African Environmental Observation Network for long-term eco-hydrological research and global change observation.

Summary: This article reviews the current status of fish telemetry studies in inland African waters and evaluates its potential applications in various fields such as water resource management. While telemetry studies are widely used in developed countries, their application in Africa is relatively lacking. Despite some limitations, the benefits derived from telemetry studies in managing Africa's water resources are significant.

Summary: In the treeless grasslands of the central Kruger National Park in South Africa, the grassland's topsoil is significantly richer in nutrients compared to adjacent savannas, leading to a higher competitive strength and nutritive value of the herbaceous layer. This nutrient richness may result in greater herbivory pressure in the grassland, providing a plausible mechanism for the constraint of tree growth in these landscapes.

Summary: Human activities both aggravate and alleviate streamflow drought, with water abstraction being the dominant aggravating factor and water transfers effectively reducing drought. Reservoir releases can alleviate drought in dry season but change flow seasonality. Land use has a smaller impact, with both positive and negative effects observed.

Summary: Studies on the economic impacts of invasive alien species often focus on ex-post assessments of control options, but ex-ante assessments are also necessary. This study developed a simulation model to assess the potential impact of the polyphagous shot hole borer on South Africa, taking into account the dynamic mutualistic relations between the beetle and its symbiotic fungus. The model predicted a steady growth in beetle populations and their negative effect on various industries and ecosystems, highlighting the importance of ex-ante economic assessments in invasive species management.

Summary: In southern Malawi, smallholder sugarcane farmers prefer to access weather forecasts through radio, with women also showing a preference for knowledge brokers. Farmers with higher levels of education prefer to obtain forecasts through the internet and cell phones. Most farmers find weather forecasts reliable, timely, and understandable, with men showing a slightly higher preference for them than women. Understanding gendered preferences and barriers to climate information access is essential for equitable access to the benefits of adaptation.
